NEW: cylindrical multigrid FDTD
...
this is a new multi grid approach for the cylindrical FDTD.
The FDTD domain will be split in two regions in radial direction.
The "inner" region will have half as many disc-lines in alpha direction and therefore allow for a much larger timestep which increases the simulation speed.
Todo:
- currently only a homogeneous disc is allowed in alpha direction
- some extensions have to be tested and prepared for this approach (e.g. pml)
- speed enhancement and more efficient memory usage
- lots and lots of testing...

Operator: GetNodeArea & Update/fix in Calc_EffMatPos method
...
- new method GetNodeArea will return the area of a node for a given direction
- methods Calc_ECPos & Calc_EffMatPos now const
- Calc_EffMatPos in Operator class updated to use new functions GetMeshDelta & GetNodeArea
- Calc_EffMatPos introduced (fixed) in Operator_Cylinder (need some testing)
- treatment of E_alpha=0 at r==0 moved from Calc_ECPos to Electric-BC

changed openEMS dumps from drawing units to unit of meters
...
the better approach is to create a new class (e.g. Dump)which contains all dump formats (currently vtk and hdf5). This class will then be responsible to choose a dump mode: in drawing units or in meters
